Crystal structure of Tyrosine-tRNA ligase mutant complexed with unnatural amino acid 3-o-methyl-Tyrosine

Function

[SYY_METJA] Catalyzes the attachment of tyrosine to tRNA(Tyr) in a two-step reaction: tyrosine is first activated by ATP to form Tyr-AMP and then transferred to the acceptor end of tRNA(Tyr).[1]

About this Structure

4hpw is a 1 chain structure with sequence from Methanocaldococcus jannaschii dsm 2661. Full crystallographic information is available from OCA.
